The Unique Control LKB automation unit with built-in actuator offers intelligent control for LKB butterfly valves used in all applications. This straightforward all-in-one actuator offers superior flow control, hygiene, durability and reliability.
How it works
Operating principle
The Unique Control LKB uses an air spring, which enables the unit to be operated at a significantly lower air pressure compared to control units using a conventional mechanical spring. This reduces wear thereby eliminating the need for maintenance.a
When air enters the Unique Control LKB, the built-in solenoid valve diverts the flow either above or below the piston. The helix inside the piston transfers the vertical movement into a rotation ensuring smooth valve operation. The design enables the Unique Control LKB to operate at an air pressure of only 3 bar.
Integrated air surveillance system
A built-in pressure sensor monitors the air supply. In the event of a critical drop in air pressure, the actuator sends a warning signal, but continues to operate. In the event that the supply of air is cut off, the actuator also sends a warning signal, maintains its position and continues to operate after resolving the problem.
Switching from NC to NO
Changing the normally closed contact to normally open position is easy. Simply open the top cover, loosen the screws, lift up and rotate the top 180°, then re-assemble it.
